HOUSE-WIRING FIXTURE.

SPECIFICATION forming part of Letters Patent No. 542,924, dated July 16,1895.

Application filed April 20, 1895. Serial No. 546,568. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES F. CASE, a citizen of the United States,residing at Akron, county of Summit, and State of Ohio, have inventedcertain new and useful Improvements in I-Iouse-l/Viring Fixtures; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the lettersof reference marked on the accompanying drawings, whichform a part ofthis specification.

My invention relates to insulators for housewiring. Its object is toprovide a conduit or passage-way of any insulating material for incasingelectric wires passing through the plaster or its equivalent in a room,and to provide for the passage of the gas-pipe also through the samewhere combination fixtures are used.

In the accompanying drawings, Figure l is a section view of my improvedinsulator. Fig. 2 is a plan view of the same. Fig. 3 is an end view of amodified form of my device. Fig. 4t is a section view of the form shownin Fig. 3. Fig. 5 is an elevation of the form shown in Fig. l.

In passing electric wires through the ceilings and walls of a room whenthey are embedded in the plaster much difficulty is experienced insecuring them just in the proper place by the plasterer, and they arevery liable to sut'- fer abrasion of the insulation. IVhere rules ofsafety require that tubes of insulating material be used to inclose thewires where they pass through the plaster the practice is to have thewires embedded in the plaster, and the wireman digs away the plasterimmediately around the wires to admit of the tubes being slipped on thewires and inserted in the opening.

It is evident that the tubes will be somewhat insecure in the more orless irregular orifice thus made, and obviously this plan of operationwill be unsatisfactory and objectionable to both the plasterer and thewireman.

To overcome the defects above referred to I have provided a devicewhereby the insulating-tubes can be put on the wires and held rigidly inthe proper position before the plas ter is put on the lathing.

Referring to the accompanying drawings,

A is a plate of insulating material of considn erable rigidity, havingin it, preferably at its extremities, two or more holes for the passageof screws or other means of attachment. Passing through this plate A,and extending at right angles to the flat portion thereof, are two tubesC and D, which are made integral with the said plate A. Fig. 3 shows amoditied form of my insulator, in which another tube F., also integralwith the said plate A, intersects the plate at right angles. It ispreferably intermediate of the tubes C and D and in juxtaposition withthem. The tube E is of sutlicient caliber to admit of the customary sizeof gas-pipe passing through it, this form of insulator being designedfor combination fixtures.

Fig. 4 shows my combination insulator in use. H is a joist or studdingfor side wall or ceiling, as the case may be, the mode of attachmentbeing practically the same in each location. G represents the lath and Fthe plastering. A cleat J is secured between two joists (or studs) inany suitable manner. This cleat contains an aperture, into which thetubes C D and E are inserted until the flat portion A comes in contactwith the cleat, where it is secured by screws passing through the plateinto the cleat. The cleat is secured at such distance from the outeredge of the joist that the outer ends of the tubes shall be iiush withthe surface of the plaster when in place. The wires are first secu redabout where they are to be used by ordinaryinsulators. They are thenbent to their designed place and my improved insulating device slippedover the wires and secured by the cleat in the exact proper position,after which the laths are built around the tubes for the plastering.

lVhen my improved combination insulator is used the method followed isvery similar'. The gas-pipe being in position, the wires are bent upparallel with it at the proper distance therefrom and my insulatingdevice inserted on the wires and pipe and fastened in the aforesaidmanner.

My invention is as well adapted for side lixtures as overhead fixtures,and for use in connection with walls or ceilings which are plastere'd,but which may be wainscoted, or of wood or other material used for suchpurpose.
